The WITTRA IOT Out Of the Box is a wireless sensor kit that utilizes a cloud-based (subscription plan) API that can be deployed on a site to monitor objects. These devices can function in tough environments such as industrial sites and areas with weak connectivity. It uses sub-GHz frequency bands which allows the signal to penetrate dense building infrastructure. This kit utilizes HTTPS, DTLS for security. HTTPS is an extension of the HTTP protocol. HTTPS communication is encrypted using Transport Layer Security (TLS). DTLS is a communications protocol providing security to datagram-based applications by allowing them to communicate in a way designed to prevent eavesdropping, tampering, or message forgery.
1) The kit was well protected during shipping, it was cushioned inside two boxes with the hard plastic case.
a) The kit case is obviously designed for tough environments such as a construction site and industrial workplace.
**NOTE: Performed drop test from 4.5 feet and one "tab" opened up which caused some contents inside of the case to fall out of place (see image below). ** To solve this either the user can use some sort of a lock or redesign the case. Using a Pelican case would also solve this problem.
2) The kit came with all necessary cables besides an ethernet cable.
Setting up the devices:
To remove the protective cap on top of the tag WITTRA provides an east tool where the user will attack it to the tag and push towards the tag and the top will pop off, shown in the photo below.
3. Once all tags were charged and updated I wanted to get the gateway setup and running. This consists of:
4. The next step I took was logging into the portal. The portal can be accessed by going to https://portal.wittra.se/
The above photo shows the moment after I uploaded the "Batch Token". You can see the mesh router in blue and the tags in red. One issue I found difficult was figuring out which tag is which after they were labeled, there should be a way for the physical tag or router to be identified with what's in the portal. The S/N are printed on the devices but are very small.
Once all devices were inserted into the portal you will get a project layout like shown above. You will see 1 gateway, 3 mesh routers, and 4 tags which were in one kit. Now, these numbers will change depending on the size of the project.
The above image shows the "Quick Configuration". The user is able to assign each device a name, group, and color code. Which makes the devices easy to find on the portal as long as the user places the intended devices correctly. I could see this being an issue without putting some sort of tape or sticker on each mesh router/tag for identification.
The above screenshot shows what the tag records, I attached this tag to my John Deere tractor on my site. These tags record several data points including accelerometer, gyro, magnetometer, battery %, Temperature, Movement, and the ability to add on more options.
The above image shows another view of the dashboard when all of the devices are running. It gives the user plenty of information on the devices. The name, power, last seen, last boot, firmware, and actions are included.
This kit would be extremely useful in a permanent industrial setting, these tags are easy to mount using the provided straps or industrial tape. A permanent setting would allow a team of technicians to continuously monitor the dashboard. I could see this kit being used in a construction site setting but it requires the company to hire someone to set up, deploy, and monitor the system. The biggest issue with this setting would be updating all the devices. This could be solved by creating an app for a cellphone or tablet so the technician doesn't have to be at a desk to continue monitoring. Another interesting option would be to set up some sort of an "alert" text or email to be sent out if a device goes out of range or if the device fails to communicate with the gateway. This could be a workaround to having a technician continually monitoring devices.
Another issue I had was updating the devices, some tags would take longer than others, I had an issue with one tag where it wouldn't update at all or communicate with the portal. I tried several different troubleshooting methods. At this point, if I was a subscribed user I would have contacted WITTRA support to open up a support ticket.
Overall, I believe this product is ready to go into production and for it to be utilized in an industrial setting. I believe the documentation is great, it's very simple to use and to understand.
The biggest addition would be a mobile app to go along with this system. Nice job WITTRA.
